Two-Dimensional Motion

The rate of change of the angular velocity of a rotating body

• centrifugal force

• angular acceleration

• radian

• gravitational force

The angle in radians (degrees, revolutions) through which a point or line has been rotated

• arc length

• moment of inertia

• angular displacement

• rotational motion

The quantity of rotation of a body, which is the product of its moment of inertia and its angular speed

• angular momentum

• angular displacment

• rotational kinetic energy

• center of mass

Change of angle per unit time, measured in radians

• centripetal force

• rotational dynamics

• angular speed

• torque

The length of a curve, measured in meters (the radius multiplied by Pi)

• universal gravitation constant

• radian

• center of mass

• arc length

A point representing the mean position of the matter in a body or system

• center of mass

• moment of inertia

• tangential speed

• arc length

The apparent acceleration, equal in magnitude and opposite in directions to the centripetal acceleration, drawing a rotating body away from the center of rotation, caused by the inertia of the body

• radian

• moment of inertia

• centrifugal acceleration

• torque

An apparent force that acts outward on a body moving around a center, arising from the body's inertia

• torque

• universal gravitation constant

• tangential speed

• centrifugal force

A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving

• centripetal force

• rotational motion

• tangential acceleration

• angular motion

The acceleration toward the center of rotation that holds an object in its circular motion

• rotational dynamics

• centripetal acceleration

• radian

• angular speed
